Pocket calculator.

[Ian Field]

Anyone know where I can buy a pocket calculator that has an actual slide
switch on/off switch - not push one of the buttons to turn it on?

Don't need a fancy scientific or graphic calculator - just the basic
arithmetic for catching out the bogus offers in the supermarket.

The problem is; all the calculaters I can find have push button on & off
which get bumped in my jacket pocket, constantly getting switched on
unintentionally in my pocket - when I want to use it the battery is flat.

Kinda defeats the whole point of a pocket calculator!

Thanks.

Solar ones don't need on off switches and from memory they used to woork
under shop lighting.

AFAIK they won't store enough energy from the occasional excursions out of
my pocket for a few seconds to check a so called special offer - maybe I
could install a halogen lamp in my jacket pocket and carry a SLA battery in
a backpack.

A REAL on/off switch is what I'm looking for.

I had a casio once that unfolded like a clam shell with solar cells on one
half and the calc on the other, it worked in shops just fine. Of course now
I have a talking one much to the annoyance of people around me.

Wouldn't mind one that loudly announces that the advertised special offer is
actually a disguised rip-off.

Suggestion. DIY switch. If its a calc that takes ordinary batteries, get a
small pice of double sided copper clad pcb, and solder a small two core wire
to either side. Insert between batteries, bring wire out and solder small
switch on end of wire.

That may yet be an option - but not until the battery needs replacing - the
last one with switch (that got broken) originally had 2 expensive button
cells, I hot melt glued a CR2032 holder complete with battery on the back of
the calculator.

No reason why, on the next one I couldn't include a switch.

_Anything_ with wires hanging out of it is a suspect bomb, and the OP
will be arrested as a terrorist. The area around the supermarket will
be cordoned off by the police for six hours while they decide whether
the device is "viable" or not. Am I alone in finding the use of the
word "viable" to describe a suspect bomb a bit odd?

A 99p WH Smith/Morrisons calculator has a clear case so you can easily see
its just a calculator, and its also too small to be "viable".

But so far; the one I carry in my jacket pocket hasn't run down - in fact it
might actually cost about the same to buy another calculator when it does,
as the price of a battery!

An alternative would be one with a clamshell case, making it impossible to
activate the on/off button.
