ITW Lumex Switch Snap Action Switches employ “butterfly contacts” which provide simultaneous switching of multiple circuits, self-cleaning contacts and which have contact design which is resistant to vibration. These switches are used in special purpose applications where consistency and long life are critical.
ITW Lumex Switch Series 16 Snap action Switches feature the Butterfly double break momentary switch mechanism. This offers the capability of handling high (or low) current loads in a small switch and gives the options of controlling two circuits with the Form Z switch circuitry.
This unique design has a DPDT-DB (Form ZZ) contact arrangement, or can be wired externally to provide two commons to form standard DPDT (Form CC) circuitry. This switch can control up to 4 isolated circuits.
