BDG – Mechanical Micro Switch
Country of manufacture is not indicated, suspect Taiwan/China
Material: White plastic bodyTYPE: HC 050K4
Rated maximum: 2.5A @ 250V ACSpade terminals (4.75mm wide)
Normally CLOSED contacts
The mechanical sensor can be viewed inside, along with the spring HOWEVER the micro-switch it activates is TOTALLY ENCLOSED and SEALED
Very sensitive switch action, just moving the switch mechanical sensor by 2~3 degrees activates the switch (going open circuit) quickly and cleanly (no resistance lag)
Normal position (closed) tested as VERY LOW resistance.
Physical movement of the mechanical sensor is smooth, spring supported action (returns to rest position under spring pressure) I did not measure the torque required to push the sensor but it is a “light touch”
These are general purpose domestic and industrial appliance closed door/open door & limit switches but we actually used them as simple limit switches on a custom project – low cost and very effective. Think outside the box, these switches can be very handy in situations where physical movement needs to be detected at low cost.

DIMENSIONS:
Irregular shape but I will attempt to give the measurements (micrometer read)
Front: 25.25mm x 29.5mm
Front to Back: 25.9mm
Mechanical sensor protrudes 15mm forwards from the front in the “normal” position, when physically pushed, this sensor lies flat with the front.
Panel cutout required: 22mm x 27mm
Fixing to the panel is achieved with a small “slot” to one side (0.5 ~ 0.6mm thickness) and on the opposite side is a push snap lok
Various safety standard stampings made into the rear of the switch

COSMETIC CONDITION:
NEW Unused
CLEAN
NO damage at all to the switch in all respects

Each switch is individually packed in sealed clear plastic
