Panel by Loudest Warning: http://www.loudestwarning.co.uk/

The module contains 3 analog switches that operate as SPDT switches. Each can be momentary (logic low is A -> A/B, logic high is B->AB) or latching (switch changes state on logic high). The analog switch can accept the full power rail voltage range.

A manual push button is included
