Actuation Information
Series 18 – Technical Data
The series 18 is ITW Switches’ smallest microswitch. It is a single pole with a self cleaning
‘butterfly’ mechanism. This gives a high performance switch in terms of life and load ability,
switching from logic loads to 8A max. The series comes in gold double break, snap action
contacts with gold solder terminals as standard. PCB terminals and custom brackets and
actuators are available as non-standard options. The terminals are inserts moulded into the
base, this coupled with the lid being bonded to the base gives a totally sealed switch up to the
button opening. Its small size, high performance and high temperature rating, provide a switch
that is suitable for many demanding applications. The switch has UL and MIL-Specification
approval according to version.
• Form Z contact – covers all switching
• Snap action – uses high integrity butterfly
• Solder terminals – for superior electrical

The series 18 microswitch is incorporated in the popular 78-2510 pushbutton switch. There are
also a number of actuators designed to fit directly onto the microswitch.
These include leaf, roller levers and pushbuttons.
