Technical Information
Series 76-94
The 76-94 Series has been designed to cover a wide range of harsh environmental applications.
The range is available in 3 styles, push-button, rotary and panel lamp.
The push-button comes in 4 button styles with 3 colour options and has solder/faston
terminals as standard. The rotary is a single pole, 2 position, snap action switch with green or
red spot indicator on the black actuator. To complete the range an indicator version is available
with red, green or amber lens.
The entire range is panel sealed to IP67 and due to the construction and the materials used,
are all capable of surviving the impact of a 5kg mass dropped from 40cm (20J). All the bezels
and the actuators of the push-buttons and rotaries are made from a non-sparking zinc alloy
whilst the panel lamp lens is manufactured from polycarbonate, which maintains the
specification of the range.
Non-standard options for the range include custom colours, PCB terminals, gold contacts and
2 pole variants.
The features of the Series makes it ideal for robust, potentially explosive environments, such
as the mining industry.
Specification
The push-button and rotary variants utilise ITW Switches’ proven Series 16 snap action
microswitch.
