This is a mini pushbutton momentry switches holder with suspension tabs speacially designed for Replica MPP clamps from TCSS for assembling functinal bubble strip/card activation system. It has two spots to hold metal springs for spring-loaded bubble strip/card (optional) or just plastic tension tabs can be used.
"Suspension tabs" or "springy tabs" are made to hold bubble strip/card tight and act as suspension when you press the bubble strip/card to return it back to the original position. So switches holders with "suspension tabs" are printed in flexible plastic, switches without them can be printed in non-flexible materials like acrylic plastic and metal, because metal tabs are not elastic obviously, so you need springs instead of "suspension tabs" or some other way to return bubble strip back when you push it.
For perfect fit may require minor custom modifications.
