Littelfuse 59050 Miniature PCB Mountable Reed Switches

Littelfuse 59050 Miniature PCB Mountable Reed Switches measure 22.86mm x 4.57mm x 4.32mm and offer a choice of normally open, normally open high voltage, and change over contacts. The 59050 switches feature molded standoffs to allow board washing and are capable of switching up to 265VAC/300VDC at 10VA. Applications include position/limit sensing, security system switches, and door switches.
