This range of switches features a robust high quality housing with 1 or 2 sealed SPDT microswitches and has been designed for use in environments where explosive gases can be present (e.g. gas fields, oil rigs & chemical plants etc).

Microswitches can be requested for single or dual simultaneous operation (DPDT switching). Environmentally sealed or hermetically sealed microswitch options are available. 

One of the benefits of the Perseus range is the separation of the flameproof and adjustment chambers allowing adjustment of the set point with power on and the switch in operation. The housing is available with one or two electrical entries.
