I'm looking for 3 of the old type MK Metalclad "Secret Key" gridswitches, the ones that fit onto a rail using a clip top & bottom of the switch and then are covered by a silver coloured steel front plate with rounded corners . Anyone any ideas?
Apparently the newer type (plastic) wont fit because of the front panel aperture sizes and I need to tamper proof 3 out of 8 switches on a panel.
