Safe-T-Mate Personal Safety Alarm has a switching mechanism that uses a surface mounted magnet which releases in any direction. The alarm will sound at the moment the magnet is pulled away from the metal face plate and can only be silenced by re-applying the magnet. If she has the box attached to where she is sitting and the cord attached to her clothing the alarm will sound when she stands, she can then grab her walker and remove the cord from her clothing to put back on the box to quiet the alarm.
