SPIDER Automation Self-Lock Push Button Switch KFC 8.5×8.5mm C Type | Latching Square Power Switch
Description
SPIDER Automation Self-Lock Push Button Switch (KFC 8.5×8.5-C) is an essential electromechanical component designed for engineers, makers, and repair technicians looking for dependable latching control. Measuring 8.5 by 8.5 millimeters, this square push button switch features an internal self-locking mechanism that keeps the circuit closed or open after actuation, making it ideal for power control applications where momentary contact is insufficient.
Constructed with high-quality materials to withstand operating temperatures from -25°C to 65°C, the switch delivers consistent tactile actuation with a balanced 200gf operating force. Whether you are designing custom control panels, prototyping electronic modules, or repairing household appliances, this switch guarantees long-term electrical stability and mechanical endurance.
Key Features
- Square 8.5×8.5 mm Design: Compact footprint tailored for high-density printed circuit boards and tight control panels.
- Self-Locking Latching Mechanism: Toggles and holds its state firmly upon depression until released by a second push.
- Durable Construction: Built using robust internal contacts and housing to ensure heavy-duty reliability.
- Low Contact Resistance: Maintains strict electrical integrity with less than 50 mOhm resistance for optimal current transfer.
- High Insulation Resistance: Exceeds 100 MOhm resistance to prevent leakage currents and electrical shorting.
- Balanced Operating Force: Requires 200 ± 80 gf actuation force for a positive, tactile user switching experience.
- Extended Lifecycle: Rated for thousands of reliable mechanical cycles to endure years of active usage.
- Wide Temperature Tolerance: Functions seamlessly in harsh thermal environments ranging from -25°C to 65°C.
- Versatile PCB Mounting: Designed with standard through-hole terminal pins for secure solder joints.
- Precise State Control: Ideal for power ON/OFF toggling and mode selection in electronic gear.
Benefits
- Maintains Circuit States: Removes the need for holding down buttons or utilizing complex latching relay circuits.
- Space-Saving Footprint: Miniaturized dimensions allow multiple switches to be clustered on small control interfaces.
- Long-Term Reliability: High lifecycle endurance minimizes maintenance or replacement frequency in finished equipment.
- Safe Power Handling: High dielectric withstand voltage ensures safe operation under standard low-voltage DC/AC loads.
- Cost-Effective Prototyping: Essential staple component for laboratory workbenches, hobbyist kits, and electronic manufacturing.
Applications
- Consumer Electronics: Power ON/OFF toggles in audio gear, small appliances, and household devices.
- Custom Control Panels: Mode selection switches for industrial test jigs, laboratory equipment, and custom machinery.
- DIY & Maker Projects: Prototyping microcontroller circuits, Raspberry Pi enclosures, and Arduino breakout boards.
- Automotive Dashboards: Auxiliary lighting switches and secondary accessory control buttons.
- Telecommunication Devices: Signal routing and feature-activation buttons on legacy communication gear.
