<p>Snap Action Switches, also known as micro switches, are switch devices that are used to open or close an electrical circuit at a rapid speed. These highly sensitive switches are often used in irrigation systems, semi-trailer systems, timing devices, office equipment, test instruments, medical and dental equipment, HVAC systems, valves, and manually operated devices, among others.</p><p>DT-2RV23-A7 Snap Action Switch from Honeywell is a standard basic micro switch. This Honeywell Switch is designed with two independent single-pole double throw circuits in a single housing. Both these circuits are activated by one actuator. It has temperature tolerance to 82 °C [180 °F]. The design of this DPDT Switch allows various wiring combinations, as well as mounting interchangeability with type Z switches.</p>
