Electrical switch - help please to identify

[111KAB]

In amongst some switches I was about to dispose of I came across this .....

which I think is a 2 way switch to switch between 2 batteries (with an off in the central position) - if so I may be able to make use of it however I cannot see how the various wires connect to the switch. I presume there must be some kind of adaptor - any help appreciated. The switch says MF 30 volts 5 amp. Sorry about quality of photo. Thanks for any help.

you cant do much with 5 amps

As sailorman says, you can't do much with it, and you definitely couldn't use it to switch between batteries. Is it really a switch? Hard to tell, but it looks like it might be a relay.

Circuit breaker ? push on, pull off.

Looks like switch for operating an electro pneumatic or electro hydraulic valve.
