3. 70’s – 80’s Clamp-On Switches
that say what they do, in English
Mopeds (motorized bicycles) had less strict equipment laws than motorcycles did, and still do. They don’t need to have turn signals, or a permanently-on head light. The US DOT equipment laws dictate what the switches do, what they say and where they go. Engine stop always goes on right, reachable by right thumb. Lights and horn are reachable by left thumb. After 1972 US DOT compliant switches had English words. After the mid-80’s US DOT allowed international icons.

On a late-77 to 86 Puch, with brown and blue/black horn wires,
if you remove this switch, and unplug the horn, the engine will not run.
The blue wire with the black stripe is an “external ignition ground” wire.

1 HI-LO-OFF HORN $16 cap used, like new, tested
2 LO-OFF-LO HORN $14 cap used, like new, tested
3 ENGINE RUN-OFF $14 cap used, like new
Inside the cap, the horn button spring gets weak, or the rivet gets rusty.
On most bikes, that just makes the horn weaker, but on a ’77-later Puch,
that causes the horn to stay on all of the time (so does a loose clamp).

These clamp-on switches are almost the integrated type, because the switch hangs over part of the control. Magura made the switch base and Merit made the switch, both in 1970’s Germany. The switch bases broke easily, and so the supply ran out early on. They were on US-model mopeds: deluxe Puch models 1978-86, and deluxe Kreidler MP-19.
