Their extremely small size and light weight suit two series of illuminated toggle switches well for use in handheld devices or front-panel interfaces. The B series subminiature and G series ultra-miniature switches from NKK Switches feature toggle actuators made of clear polyamide, so the LED color fully illuminates the actuator. The B series also has a fully illuminated patent-pending bushing.
The switches in the B series measure 0.516 in. high and wide and 0.346 in. deep. Their toggle is 0.248 in. long. The G series switches are only 0.276 in. high and wide and 0.177 in. deep. Their toggle is 0.150 long. Standard 0.100- by 0.100-in. pc-board terminal spacing allows high-density installations. Both series are rated at 0.4 VA at 28 V ac-dc maximum and are available in single-pole maintained circuit options of On-On and On-Off-On. They can be specified in straight PC, right-angle, or vertical-mount terminations.
Red, green, amber, and bicolor red-green LEDs are available. Both series are rated for 100,000 mechanical operations. The B series electrical life is rated at 50,000 operations minimum and the G series at 100,000 operations. Contact the company for price and availability information.
CIT Relay & Switch's J115 series relays come in three versions: PC termination, combination PC and QC for contacts, and panel-mount QC for both coil and contacts. The relays exceed UL standards—40-A contacts, 2 hp, and Class F insulation (approved for maximum coil temperatures of 140°C). All versions are available with single-pole single-throw (SPST) normally open (NO), SPST normally closed (NC), or single-pole double-throw (SPDT) contact arrangements. They offer heavy contact load, strong shock and vibration resistance, and numerous coil voltage choices ranging from 3 to 110 V dc and 12 to 277 V ac. Volume prices start at $0.89, and they're available now. For more details, go to www.citrelay.com
Capable of switching 16 A at 250 V ac, the G5LE-E series of power pc-board relays comes in the industry-standard 19.6- by 22.5- by 15.2-mm "sugar cube" and pinout for drop-in compatibility with existing pc-board layouts. The series includes 5-, 12-, and 24-V dc coils, and power consumption is 360 mW. SPST NO and SPDT versions are available. Prices range from $0.75 to $0.85 in 5000-unit quantities. Delivery is from stock to eight weeks. Visit www.components.omron.com
