This keyswitch uses tubular keys with black plastic inserts to easily identify them. It has 2 positions and the key is removable from both. There are 4 connection terminals, however, it is not a regular Double Pole Single Throw (DPST) switch, but rather a dual Single Pole Single Throw (SPST) change-over switch as each pair of contacts is in the opposite state to the other.
So it could conceivably be wired to create a Single Pole Double Throw (SPDT) switch, or used in its native state to independently switch one circuit on while switching another off with complete isolation.
Contact rating is 2A, 250VAC.
