Rare Hella Alarm Signal sequence switch clock Price: $680
|
Hella Alarm Signal sequence switch clock, very good condition, working very well, +20 USD shipping
It was mounted in the 50ies in German police, fire and ambulance VWs like VW Oval and T1 Fire bus. It works like an egg clock. When the sequence switch is on, the high low fanfare horns are on.
The chrome is dirty but very good and without dents. The knob is very good and working. The case is also good and without dents. Even the 2 small black rubber pieces are on the rear for cable protection. In total is looks like new old stock. The rear diameter is 5,5 cm, the front face diameter is 6,5 cm and the knob diameter is 4,0 cm.
The name in German is "Schaltautomat" and Hella made three different versions. The switch for sale is Hella # 91/31. It has on the chrome face number 1, 2, 3, 4. Depending on the setting the fire or police signal runs 1 to 4 times.
You can connect 3 cables to the switch. One ground cable and behind a cover are 2 screw terminal connectors which are marked on top of the cover with “H” and “T”.
H is in German for “hoch” for the high tone horn wire, e.g. for a 520 hz horn.
T is in German for “tief” for the low tone horn wire, e.g. for a 390 hz horn.
If you put horns behind the switch, you will listen to the special police fire department sound. So cool!
