The HUB-T Amseco Potter Hold Up Switch-Two Button provides two sets of momentary or latching DPDT contacts for actuating surveillance cameras or other security applications, in addition to the hold-up signal. The two sets of contacts may be used independently of each other, or they may be wired in series with a jumper wire for additional protection against false alarms. See illustration on page 2.
