Identification of switch type casing type or housing type

Question

I don't know what or how to identify this switch.

a picture of a switch on my knee

Its dimensions are:

29.5mm by 25 by 21.5 tall. It has a lug for a screw on the side you can't see it is actuated by a pin on a separate housing

Thanks

Stupidly I hadn't looked at another image I had which clearly stated 'XE2SP' which promptly gave me the manufacturer and terminology.

SCHNEIDER ELECTRIC / TELEMECANIQUE - XE2SP2151 - CONTACT BLOCK

Maybe an Eaton or Cutler-Hammer safety switch, though it's really difficult to guess from the limited information.

Can somebody let me know what form factor this is

In EE (and physics apparently) form factor is defined as: -

The ratio of the RMS value to the absolute mean of a sinusoidal wave (especially to that of an alternating current)

Taken from here

If you are wanting to know the form factor as defined by EE guys then it doesn't apply to a switch - it's to do with electrical signals.

\$\begingroup\$ Point taken but not very helpful. How about modifying the question or offering better terminology \$\endgroup\$

\$\begingroup\$ @PaulSullivan - how about you define what you mean by form-factor because the only meaning I understand is as stated in my answer. \$\endgroup\$

\$\begingroup\$ @Andyaka Sure. ATX form factor, for example. It basically means shape, size or some other physical dimension (or conformity to a standard that defines those). Loose term, but pretty common IME. \$\endgroup\$
