Called DM3, they are “available in actuator options including pin plunger [no lever], 13.3mm hinge lever, roller lever and simulated roller lever,” according to distributor New Yorker Electronics, which is stocking the parts. “DM3 series offers terminal options: solder lug, straight printed circuit pin and right or left facing right-angled printed circuit pin.”
Ultra-sub-miniature-micro in this case means a 12.8 x 5.8 x 6.55mm body.
The switches are SPDT, so they can also be wired as SPST normally-open or normally-closed.
Without a lever, actuator travel is 1±0.3mm (0.7mm max pre-travel, 0.1mm min over-travel, 0.2mm max actuate-to-release) requiring 100±40g force – return force is 50g. At the end of the various levers, this equates to 35 or 40g to actuate and 15g return.
‘Simulated roller’
The switches are UL certified (T85, 10,000 cycles) to 3A 250Vac general purpose, 3(0.5)A 250Vac resistive-motor or 3A 30Vdc resistive.
Initial copper alloy contact resistance is ≤50mΩ, and operation is over -40 to +85°C, 10,000 electrical cycles and 100,000 mechanical cycles.
Plastic parts are PBT (polybutylene terephthalate) UL94-V0.
