Catalog# TS800

DPDT Toggle Switch, ON-ON 
  Can also be used as ON-OFF

2 position

15 amp, 250V rated

Screw terminals

Mounting threads .46", use .5" hole for mounting

Comes with two nuts, one washer, and position indicator plate

Body color may vary

Can be used to switch from high to low voltage on the transformers with dual output voltages as long as the rated output current is not exceeded for each set of contacts in the switch. 

Can also be used as an ON-OFF switch -- just use two adjacent terminals on one side instead of three or six.

When wired as shown at the bottom of the power supply design page, each secondary coil is wired through one set of contacts so as long as the current rating of the high voltage rating is not more than 15 amps, the switch can be used to switch those voltages.  The switch cannot be used for the XFR3006E transformer but can be for all the other ones with dual output voltages.

USA shipping: $2.60 is automatically charged for first class USPS shipping for each fuse holder, excess shipping for multiple items ordered will be refunded. For example, order fuses with fuse holder and transformer and the fuses and fuse holder shipping will be refunded.
