This is a boobytrap firing device (pin withdrawal type).
This fuze is based on Soviet MUV design. The short striker-closed end design is probably used to prevent entry of sand. The pin is provided with a shoulder (2) which is very similar to that of the MUV Igniter. It is believed the switch is used with a “schu type" mine.
No information about functioning.
Nothing else to see.
