Comparison of 8013 PCB SH Switches with Other Electronic Switches

Overview: What is an 8013 PCB SH Switch?

The 8013 PCB SH switch (often referenced in hobby and small-scale industrial parts lists) is a compact through-hole PCB-mounted single-pole mechanical switch commonly used for panel controls, user inputs and simple on/off functions. This guide compares the 8013 PCB SH switch to other common electronic switches - tactile (momentary) pushbuttons, slide switches, rotary switches, reed switches and electronic (solid-state) switches - so you can choose the right device for your project.

Key characteristics of 8013 PCB SH switches

• Form factor: through-hole PCB footprint, typically rectangular housing with actuator variants (lever, spindle, or panel knob).
• Contact arrangement: usually SPDT or SPST options, mechanical metal contacts.
• Typical ratings: low-voltage DC switching (common datasheet ranges 0.3 A to a few amps at 12-24 VDC or 125 VAC for similar small switches). Always verify actual datasheet for a specific 8013 variant.
• Durability: mechanical life commonly 10,000 to 100,000 cycles depending on build quality.

How this comparison is structured

We compare on electrical rating, mechanical life, mounting/style, contact behaviour (make/break), size, and common use-cases. Practical South Africa notes include availability at Communica branches, lead-time considerations, and which accessory parts you may need (headers, washers, or PCB cutouts).

Switch types at a glance

Note: the electrical ratings above are illustrative. For actual project work in South Africa, check the specific part datasheet or the product page at Communica for exact ratings and approvals.

Selection criteria: When to pick an 8013 PCB SH switch

Choose an 8013 PCB SH switch when you need a compact through-hole mechanical switch with clear tactile feedback, simple wiring to PCB traces, and moderate current capability. It is suitable for control panels, device power switches and student projects where mechanical actuation and visible position matter.

Electrical & mechanical trade-offs

• Contact life vs cost: mechanical contacts wear over cycles; choose higher-spec parts for higher cycle counts or consider solid-state switching for very high cycle applications.
• Current and arc behaviour: small mechanical switches can arc at higher voltages/currents. For inductive loads (motors, solenoids) use appropriate suppression (snubbers, diodes) and consider a higher-rated switch or relay.
• Debounce: mechanical switches bounce. For digital inputs use hardware RC debounce or software debounce. Example RC: R = 100 kOhm, C = 100 nF gives = R*C = 10 ms ( in seconds). Adjust values for needed delay.

Wiring examples and diagrams

Simple SPST wiring for a microcontroller input with pull-up:

MCU_PIN -----/ ----- 8013_switch ----- GND
(pull-up enabled on MCU_PIN)

Adding an RC hardware debounce to the same input:

MCU_PIN ---+--- R (100 kOhm) ---+---- to 8013_switch ---- GND
           |                   |
           +--- C (100 nF) -----+---- to GND

For switching higher currents, drive a MOSFET or relay from the switch rather than routing large currents through the 8013 switch itself.

Practical examples and SA context

Example 1 - Student microcontroller project: Use an 8013 PCB SH switch as a power or mode selector. Ensure the switch handles the standby current and add RC debounce for button inputs. Typical cost and availability: communicator-style distributors in South Africa stock small mechanical switches in bulk; check Communica's Samrand branch for collection or the Cape Town branch for local pickup.

Example 2 - Small appliance control: If your circuit switches a 12 V motor drawing 2 A, check whether the specific 8013 variant is rated for that current. If not, use the switch to control a relay or MOSFET gate. For inductive loads add a flyback diode (for DC) or an RC snubber (for AC) to protect contacts. Estimated additional cost for a small automotive relay in ZAR: R50-R200 depending on brand and stock (estimate only, subject to supplier pricing).

Availability, brands and procurement tips

Communica stocks a wide range of mechanical switches, connectors and accessories from many brands and maker-friendly lines. When sourcing 8013-type switches locally, check: exact part number, contact rating, mechanical life, actuator style and PCB footprint. For tertiary/education purchases, request VAT invoices and quote options for bulk buys through Communica's account services. Branch pickup can reduce lead time compared to courier delivery - verify stock in Samrand or Pretoria branches before planning lab builds.

Final notes

This comparison of 8013 PCB SH switches with other electronic switches is intended to help South African makers, students and technicians select the best switch for their application. Always confirm ratings and mechanical footprints from the specific manufacturer's datasheet and check local stock and lead times at Communica before finalising procurement.
