Mini-Sealed SMT Rocker Switches For Instrument Grade Applications
APEM's TR Series rocker switches are designed for infrared, vapor phase and infrared convection reflow soldering and they are washable with solvents or water and detergent. These tiny switches, with a body measuring only .372" long x .318" wide x .218" high from the printed circuit board surface are ideal for
miniaturized applications, or where space is limited.
Both 2 and 3 position single pole switches are offered in 5 electrical configurations with momentary and maintained actions. They include ON - ON, ON OFF ON, MOM OFF MOM, ON OFF MOM and ON - MOM. Ratings are 0.4 VA at 20 V max. (AC or DC), with an initial contact resistance of 20 milliohms max and electrical life of 30,000 to 60,000 cycles minimum respectively for 2 and 3 position models. All models also feature static resistance to 10KV.
A .021" gap between the p.c. board and switch body as well as outward turned 'gull wing' style terminals are incorporated to permit ease of visual inspection of solder joints, both after soldering and cleaning. Optional positioning pins are also offered for added mechanical integrity after assembly, as well as to ensure proper orientation during assembly.
All TR models are compatible with automatic placement equipment and are available on tape and reel for large volume applications. The cosmetic rocker actuators are packaged separately and come in a wide choice of cosmetic colors. They securely press fit onto the switch after soldering and cleaning.
Pricing for a typical unit, model no. TR36WS80000 is $2.81 each in 1000 piece quantities.
The highly reliable TR models will satisfy stringent requirements for hand-held remote controls and data devices, electronic test equipment, business machines, computer peripherals and numerous other applications.
