The D2HW-A221D is a sealed ultra-subminiature basic switch designed for reliable ON/OFF action in space-constrained applications. This model is configured with a long hinge lever actuator, an SPDT contact form, and straight PCB terminals for mounting without posts. It is rated for loads up to 2A at 12 VDC and uses gold alloy crossbar contacts suitable for minimum loads of 1mA at 5 VDC. The switch is sealed to an IEC IP67 rating, ensuring protection against dust and water ingress. Its compact size and wide operating temperature range of -40°C to +85°C make it ideal for down-sized mechanical modules and devices requiring robust performance.
