Description
CMV103D momentary SPDT limit switch and its features?
The CMV103D momentary SPDT limit switch is a durable, high quality limit switch that uses a short roller handle for on and off. Single Pole Double Throw (SPDT) is a switch that has only one input and switches between two outputs. This means it has one input terminal and two output terminals.
The limit switch CMV103D has a “momentary” type of operation, which means that constant pressure on the lever is required to maintain contact between the COM and NO (“normally open”) terminals. When the pressure on the lever is released, the switch automatically returns to the basic NC ("normally close") position.
