Hi Mike, the key switch is approximately 23mm in length including the two pins on the bottom, 15mm in width with the NUT and 10mm in width without the nut. The top of the switch is around 4mm thick and 15mm in width.
I am buying these for my GCSE Resistant Materials docking station project and needed schematics, but could not find any?
Posted byon Wednesday, 14 May 2014Do you mean you need the dimensions?
I have purchased some of these for Year 11 electronics GCSE Controlled Assessment - they are making security devices and alarms. Possibly a stupid question - how do you attach these to the circuit?
Posted byon Monday, 28 April 2014I don?t know which circuit you have but you just connect the two terminals on the switch as you would with a standard push to make switch. When the key is turned one way the switch closes when it is turned the other way the switch opens.
