ACTION OF SWITCH
POSITION 1 – Switch unactuated button UP
SWITCH IS ON BETWEEN ONE SIDE CONTACT AND CENTRE CONTACT (CENTRE CONTACT AND OTHER SIDE CONTACT ARE OFF)
Switch is latched in this position so this circuit remains ON.
To actuate switch press down till an audible click is heard, this is…
POSITION 2 – SWITCH CHANGED OVER – NOW ON BETWEEN CENTRE CONTACT AND OTHER SIDE CONTACT
Switch is MOMENTARY so when pressure released it returns back to POSITION 1
BUT IT HAS LATCHED and the circuit BETWEEN CENTRE CONTACT AND OTHER SIDE CONTACT remains ON

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, the photographs are representative of their excellent condition, being of one of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
